Description
本発明は、ボトルの欠陥を検査するための機械に関し、より特定すると、ボトルの底部にヒール符号を検査するための装置に関する。 The present invention relates to a machine for inspecting bottle defects, and more particularly to an apparatus for inspecting a heel code at the bottom of a bottle.
ガラス製のボトルを検査するための機械は、オペレータが、欠陥のあるボトルが製造された場所を知り且つボトル製造プロセスをすぐさま調整して型における問題点を排除することができるように型のキャビティにおける欠陥と関連付ける。ガラスの一段高くした小点(ドット)の形態の型データが、ボトルの底部のすぐ上の外壁上に存在することが多い(ヒール(修復)符号)。 The machine for inspecting glass bottles is a mold cavity so that the operator knows where the defective bottle was manufactured and can quickly adjust the bottle manufacturing process to eliminate mold problems. Associate with defects in Type data in the form of a raised dot (dot) in the glass is often present on the outer wall just above the bottom of the bottle (heel (repair) code).
本発明の目的は、ボトル上のヒール符号を読み取ることができるガラス製の容器を検査するための機械を提供することである。 An object of the present invention is to provide a machine for inspecting a glass container that can read a heel code on a bottle.
上記課題を解決するために、本発明においては、ボトルを検査位置に垂直方向に支持するための手段と、検査位置に支持されたボトルの垂直方向下方に結像領域を有するカメラと、光ビームをボトル内下方へと導くための光源手段と、光のビームを、支持されているボトルの開口部を通過し且つ支持されたボトルの底部をボトルのヒール符号へ向かって外方へと照射する光に限定するように選択的な大きさとされた円形の開口部を有する絞りと、ヒール符号を含んでいる環状の光ビームを前記カメラに向かけて反射させるための、前記ボトルの軸線と同軸の円筒鏡と、前記ボトルの底部と前記円筒鏡との間に配置され、黒い円形の中心を有して、前記ヒール符号を含んでいる環状の光ビームより内側の光がカメラに到達するのを阻止するための透明なプレートとによって、軸線を有する丸いボトルのヒール符号を検査するための機械を構成している。 In order to solve the above problems, in the present invention, a means for supporting a bottle in a vertical direction at an inspection position, a camera having an imaging region vertically below the bottle supported at the inspection position, and a light beam Light source means for directing the bottle downward in the bottle, and irradiating the beam of light through the opening of the supported bottle and outwardly toward the heel sign of the bottle at the bottom of the supported bottle A diaphragm having a circular opening selectively sized to limit light, and coaxial with the axis of the bottle for reflecting an annular light beam containing a heel sign toward the camera The cylindrical mirror is disposed between the bottom of the bottle and the cylindrical mirror, and has a black circular center so that light inside the annular light beam including the heel code reaches the camera. To prevent By a transparent plate, it constitutes a machine for inspecting a heel code of a round bottle having an axis.
本発明のその他の目的及び利点は、本明細書の以下の部分及び特許法に従って本発明の原理を組み入れられている現在のところ好ましい実施形態を図示している添付図面から明らかとなるであろう。 Other objects and advantages of the present invention will become apparent from the following portions of this specification and the accompanying drawings illustrating the presently preferred embodiments incorporating the principles of the invention in accordance with the patent laws. .
ボトル10は、駆動ベルトの互いに対向する対12によって検査ステーションに支持される。
ボトルの頂部の上方には、LEDの光ボードの形態の光源16(LEDの正方形マトリックス)が配置されている。射出された光は、拡散器18によって拡散され、次いで、絞り22の穴20内を通過する。穴は、光を、ボトルの開口部内を通過させ下方へと伝搬させ、ボトルの底部を、存在するボトルに直接関係のある情報(ヒール符号)を表しているガラスのこぶ24が設けられたボトルの基部の上方のボトルの側壁へ向かうように外方へ照射するように、選択的な大きさとされている。
The
Above the top of the bottle is arranged a light source 16 (LED square matrix) in the form of an LED light board. The emitted light is diffused by the
光は、ボトル内を通過し、次いで、ヒール符号の近くでボトルを通過した光のビームに対応する環状ビームが、ボトルの底部とカメラとの間に配置されている円筒鏡27によって、結像カメラ28の広角レンズへと反射される(フレネルレンズ26が、円筒鏡とボトルの底部との間に配置されて、光ビームの直径を小さくすることができる)。円形の黒い中心34を有するプレート32が、円筒鏡とカメラの結像面との間に配置されている。円形の黒い中心の大きさは、ヒール符号を含んでいる環状ビーム以外の光がカメラの結像面に到達しないように規定されている。像は、プロセッサ30によって評価される。所望ならば、絞りは自動化することができ、光源及び拡散器は、垂直方向に変位可能なユニットの一部分とすることができる。
The light passes through the bottle, and then an annular beam corresponding to the beam of light that has passed through the bottle near the heel sign is imaged by a
